Description
Technical field
The present invention relates to coal mine gas drainage equipment technical field, specifically a kind of triple channel Grouting Pipe and the Grouting Pipe
Overlap joint application method.
Background technique
Existing gas drainage Grouting Pipe, only one slip casting channel.Notification number is the disclosure of the invention of CN103452522B
Gas drainage wears formula plugging device and its application method, is mainly combined by A pouch and at least one B pouch combination docking group
At the combination of A pouch includes No.1 pouch, Grouting Pipe, gas leakage disposition pipe and transition piece, and Grouting Pipe is each passed through with gas leakage disposition pipe
Check valve is arranged in the Grouting Pipe in No.1 pouch in No.1 pouch；The combination of B pouch includes No. two pouches and Grouting Pipe, slip casting
Check valve is arranged across No. two pouches in pipe in the Grouting Pipe in No. two pouches, the combination of A pouch combined with B pouch between it is short
Grouting Pipe is docked by straight joint, and drainage tube passes through No.1 pouch and No. two pouches.The present invention can connect the combination of A pouch
And multiple B pouch combinations, it can be realized to the more effective injection hole sealing of sealing section drilling, more effectively avoid sealing section drilling week
The generation and development in coal wall crack are enclosed, and the present invention also can be carried out filling to minimum coalmass crevasse, so that sealing of hole effect reaches
To best.It is then at least needed using existing hole sealing technology if you need to realize to the sealing of hole of coal bed drilling and the gas leakage in later period disposition
Two Grouting Pipes are wanted, respectively channel is disposed in slip casting channel and gas leakage, and then causes entire sealing of hole equipment size larger, heavy,
Biggish trouble is brought to underground transportation.Also, it can hardly voluntarily be realized inside traditional hole packer and lead slurry, it is more if you need to realize
Section slip casting needs to be arranged again one and leads slurry pipe or multiple overflow valves are arranged；In addition when carrying out insertion plugging device to drilling, outside
There is the possibility to fall off in the gas leakage disposition pipe connect, these undoubtedly increase the unstability of plugging device work.
Summary of the invention
In view of the above-mentioned problems, including with hole-sealing grouting the purpose of the present invention is to provide one kind, leading to starch and be disposed with gas leakage
The plugging device special three-way road Grouting Pipe and its overlap joint application method of the integrated function of slip casting.
In order to achieve the above objectives, using following technical scheme.
A kind of triple channel Grouting Pipe, including antipriming pipe, single hole pipe, single-pass connector, the antipriming pipe include head end and tail end,
The tail end closing, head end is open, and the single hole pipe is attached by the head end of the single-pass connector and the antipriming pipe, institute
It states and is equipped with parallel first passage, second channel, third channel in antipriming pipe；The first passage is for injecting inorganic slurry
Slip casting channel；The second channel is to dispose channel for injecting the gas leakage of organic slurry；The third channel is to lead slurry to lead to
The both ends in road, third channel are in sealed condition；The tube wall of antipriming pipe is equipped with injected hole and the connection of connection first passage
Hole is disposed in the gas leakage of second channel, and the tube wall of antipriming pipe is equipped at least two leading for connection third channels and starches hole, the single-pass
Connector one end is equipped with stock inlet, and the other end is equipped with grout outlet and plug-hole protrusion, and the stock inlet is connected to the single hole pipe, described
Grout outlet is connected to first passage or second channel.
The first passage, second channel, third channel cross sectional shape be sector, triangle, round or ellipse.Three
The cross sectional shape in a channel is in the pattern of splicing, and first passage and third channel are sector, and second channel is circle.Group closes
The flow needs for meet slip casting and gas leakage disposition, combine the stabilization of structure.
The sectional area of the second channel is less than the sectional area of first passage and third channel.Second channel is used for air-leak section
It sets, flow demand is smaller.
Described single-pass connector one kind is filling adaptor, and stock inlet is for injecting inorganic slurry, grout outlet and first passage
Connection, the plug-hole protrusion set and are blocked there are two being inserted respectively into second channel and third channel.
The single-pass connector another kind is that connector is disposed in gas leakage, and stock inlet is for injecting organic slurry, grout outlet and the
The connection of two channels, the plug-hole protrusion set and are blocked there are two being inserted respectively into first passage and third channel.
The shape and structure of two kinds of above-mentioned single-pass connectors is suitble to individually inject a kind of slurries into a channel, avoids simultaneously
Into other channels, prevent slurries from polluting.
It further include quick coupling, quick coupling, which covers, consolidates its three in the outside of antipriming pipe, single hole pipe, single-pass connector
It is fixed.Antipriming pipe and single-pass connector one end are fixed in the banding effect of quick coupling, and single hole pipe and the other end of single-pass connector are consolidated
It is fixed.
The overlap joint application method of triple channel Grouting Pipe, includes the following steps：
S1：In the tail end of antipriming pipe, slip casting channel and gas leakage disposition channel are blocked；
S2：Antipriming pipe passes through three pouches, and the disengaging Nang Kou of antipriming pipe and pouch tightens fixation；
S3：Three injected holes are opened up on the antipriming pipe being located inside three pouches, are connected to them with slip casting channel, and
It is not connected to other channels；Gas leakage disposition hole is being opened up on the antipriming pipe being located at outside pouch, be allowed to only with gas leakage
Dispose channel connection；
S4：When infusing inorganic slurry, using filling adaptor, antipriming pipe is connect by a quick coupling with filling adaptor at this time,
Two plug-hole protrusions, which are inserted into gas leakage disposition channel respectively and are led, carries out plug-hole in slurry channel, then passes through a quick coupling for slip casting
Connector is connect with single hole pipe, then starts slip casting；
S5：During gas drainage, before infusing organic slurry, antipriming pipe disposes connector by a quick coupling and gas leakage at this time
Connection, two plug-hole protrusions, which are inserted into the slip casting channel of antipriming pipe respectively and are led in slurry channel, carries out plug-hole, then passes through one again
Quick coupling will dispose connector single hole pipe with gas leakage and connect, and be then injected into organic slurry.
Three pouch two of them are end pouch, and one is intermediate pouch, lead slurry hole and intermediate pouch is arranged in
On the antipriming pipe of two sides.
Beneficial effects of the present invention：The present invention is to integrate slip casting channel, gas leakage disposition channel, the threeway for leading slurry channel
Road Grouting Pipe disposes channel to slip casting channel and gas leakage by single-pass connector and injects slurries, realizes in multichannel slip casting structure
It is succinct, simultaneously because the reduction of number of tubes, injected in coal bed drilling more uniform when slurries, the protection of drilling is more arrived
Position.Overcome need multiple Grouting Pipes in existing hole sealing technology and caused by structure is complicated, transport is inconvenient and job insecurity
The shortcomings that.The bridging method combines triple channel Grouting Pipe with pouch, and then changes the internal structure of plugging device, realizes
Plugging device slip casting function is concentrated.Sealing of hole performance, the working performance of coal bed drilling are improved.
